Comparative study of transport protocols in WSN

The wireless sensor networks are a major technological development into the various problems in many application areas related to health, safety, environment, etc. This work focuses on sensor networks and mainly on the transport layer which must detect and avoid congestion. It is desirable that the transport layers protocols provide reliability suggestions planned solve problems of congestion and optimize energy. Several proposals have been made for alternative transport protocols, generally oriented to optimize specific aspects and / or application scenarios. We did a study on wireless sensor networks and its various transport mechanisms. We also conducted a comparative study between several transport protocols. Thereafter, we emulated two transport protocols based on two main criteria which are reliability and congestion. We are therefore interested in the results to find the most reliable protocol that provides a transfer with the least loss.
